Recently I had a beautiful experience of lucidity, somewhat philosophical.
I was dreaming to do several things but was not lucid. Then, in the dream, I walked into a room that had a mirror with my reflection.
Then i became lucid. I thought, "I see my reflection in a mirror in a dream ...? Never had happened to me."
So I started testing some reality checks. I looked at my reflected hands, looked into my eyes, said my name ... I noticed that the body was different than mine. It had some similarities though. Another thing I noticed was the movements. They were not coordinated with what I did. So what I decided to do? I went inside the mirror to the other side (the reflected side). My "other self" was amazed and I started talking with him:
Me-"Who are you"?
Other-"I am me and you are you. Where do you come from?"
Me-"From the other side of the mirror."
Other-"So I am you, too."
Me-"But you're not making the same gestures as me. This body i see is not mine. It's different."
Other-"When you dream about your mother or your grandmother, is their body also different?"
Me-"Hmmm ... No..."
I was thinking about this question as the dream was fading away. I saw a little light and a little sound as if to say that the dream was over.
